The 2.00-cent PET increase was below nominations made earlier in the month at 3.00 cents/lb, and came after feedstock September paraxyxlene (PX) contracts earlier settled up 1.50 cents/lb at 48.00 cents/lb delivered (DEL).

With the increase, US PET prices in September ranged from 70.96-73.96 cents/lb, as assessed by ICIS.

Part of the September increase also made up for a hike in feedstock PX prices in August that was not passed along to negotiated contracts for that month, a source said.
